Abstract

A rotor lock assembly (30) for use in a wind turbine (10) is provided. The wind turbine including a rotor (22) rotatably coupled to a generator by a rotor shaft (24) and a bedplate frame (78) is configured to support the generator (18) and the rotor shaft, and the rotor shaft includes a rotor lock disk (52). The rotor lock assembly includes a support frame (102) coupled to the bedplate frame, the support frame positioned adjacent to the rotor lock disk, a plurality of lock pin housings (104) coupled to the support frame, each lock pin housing of the plurality of lock pin housings configured to be positionable with respect to the rotor lock disk, and a plurality of lock pins (106) configured to engage the rotor lock disk to facilitate limiting a rotation of the rotor shaft, each lock pin of the plurality of lock pins coupled to a corresponding lock pin housing of the plurality of lock pin housings.
